Day 31
Released 30 October 2026 · PC · Action, Indie, Early Access
You were bitten hours ago. The clock in your blood is already running — and it isn't a virus. Fight through the waves of the dead, trade your nerve to a demon who was here before the city, and hold onto yourself for one more wave. Turn, and it's over.

It's nerve: the raw force of will that keeps a person human. Fight, and you generate it. Kill, and you claw back what the mark has taken. Hide, freeze, give up, and it drains.

She's never spoken to anyone who lived to report it,...
